Marie Manning (1821 – 13 November 1849) was a Swiss domestic servant who was hanged on the roof of London's Horsemonger Lane Gaol on 13 November 1849, after she and her husband were convicted of the murder of her lover, Patrick O'Connor, in the case that became known as the "Bermondsey Horror". It was the first time a husband and a wife had been executed together in England since 1700.
